Girls, could you please tell me if anyone had this experience? They were supposed to start their period, but they came late and how do I say it came, the first day had some blood flow, not much, but still, and the rest of the days had 3-4 brown discharge, could that be in pregnancy? I took a test two to three weeks ago and it was negative.
